NATO issues first nuclear statement in message to Moscow

NATO’s Nuclear Planning Group has issued its first ministerial statement on the alliance’s nuclear deterrence mission since 2007, committing to modernise NATO’s nuclear capabilities and strengthen nuclear planning capacity.

The group, the alliance’s senior body for nuclear deterrence matters, met at ministerial level in Brussels and agreed a statement recalling that the alliance’s strategic nuclear forces remain “the supreme guarantee of Allied security” and underpin NATO’s extended deterrence architecture.

Ministers agreed to continue enhancing the nuclear deterrence mission by modernising capabilities, strengthening planning capacity, and adapting to “achieve its security interests”, with the alliance committed to maintaining what it called “a safe, secure, effective, and credible nuclear posture” to preserve peace, prevent coercion and deter aggression. Allies also reaffirmed their commitment to sharing the responsibilities, risks and burdens of collective defence by investing in the resources and forces needed to deliver the nuclear mission.

A senior NATO official said the statement, brief as it is, marked a significant moment, noting it was the first of its kind since 2007 and stressing that NATO remained “a nuclear alliance” even as it also remained fully committed to its non-proliferation obligations. The official linked the statement to a broader shift the alliance has been signalling under the banner of NATO 3.0, describing a move back from expeditionary warfare towards deterrence and defence of the Euro-Atlantic area, and arguing that such a shift inevitably puts the nuclear dimension back at the centre of allied thinking, since any conflict with a nuclear-armed adversary carries a nuclear dimension from the outset.

The official pushed back on suggestions that the United States Secretary of War Pete Hegseth had merely made opening remarks and left the day’s meetings, pointing out that his first engagement of the day, in plenary format, had been his attendance at the Nuclear Planning Group itself, and said the United States was “fully leaning in” to NATO’s nuclear sharing mission built around dual-capable aircraft. The official said the United States, the United Kingdom and France were all visibly modernising their nuclear forces, and that Washington had repeatedly reaffirmed its nuclear guarantee to allies regardless of separate changes to its conventional posture, including reported adjustments to its B-52 bomber fleet, which the official said had no bearing on the US nuclear commitment.

Asked by the UK Defence Journal what the statement’s reference to strengthening nuclear planning capacity actually involved, the official said it was about ensuring NATO’s nuclear capability remained fit for purpose, with the flexibility and credibility to deliver deterrence, and that this rested on having the right planning and communications in place so that allies could make decisions “at the speed of relevance”. Pressed on whether this meant NATO needed more tactical nuclear warheads given Russia’s development of lower-yield weapons, the official declined to be drawn into specifics, repeating that the goal was a credible, flexible nuclear posture able to make Moscow “think again” before any escalation to tactical nuclear use, and to restore deterrence if required.

On France’s separate nuclear forces, the official said Paris’s offer was different in nature from the arrangements under which the United States and the United Kingdom cooperate with allies, but that French nuclear forces nonetheless provided “another center of decision making” that added to overall deterrence, a development the official said had been broadly welcomed across the alliance, with a number of allies interested in exploring what working with France on this might mean in practice. On the American nuclear umbrella itself, the official said there had been no discussion of any change, dismissing any suggestion that the talks had touched on the United States transferring nuclear weapons to allies and describing the extended guarantee as reconfirmed “beyond doubt”.

Asked directly whether the statement amounted to a message to Moscow, the official said it was, first and foremost, a public statement that Russia would doubtless read alongside everyone else, calling it a signal of allied resolve that extends to the nuclear dimension, and one that reflects the position taken by the current United States administration on the importance of NATO as a nuclear alliance. Asked about Russia’s nuclear capabilities in the Arctic, the official declined to single out the region, saying the alliance’s response was to extended-range Russian capabilities generally rather than to any one theatre.

Pressed on the timing of the statement and the underlying report that ministers had agreed, the official declined to link it to any single event, such as the collapse of the Intermediate-Range Nuclear Forces treaty, the reduction of US conventional forces in Europe, or Europe’s deep-strike capability gap, attributing it instead to years of accumulated work given fresh impetus over the past year, and to the wider reorientation of the alliance towards deterrence and defence, alongside a need to manage escalation risk after repeated Russian nuclear rhetoric over Ukraine.

Closing the session, the official said the core message for Moscow was simple, that NATO remains a nuclear alliance and is taking deliberate steps to keep that capability credible, survivable and adaptable.
